OM-3 ASTRO at a glance.
Experience creative freedom redefined under open skies. The OM SYSTEM OM-3 ASTRO is a dedicated astrophotography camera designed to push beyond daylight, capturing stars, galaxies, red nebulas, and nightscapes with confidence and precision. From glowing horizons to silent, remote dark skies, it lets you explore the universe and your creativity, wherever the night takes you.
Dedicated power for astrophotography
A dedicated astrophotography camera engineered to capture faint Hα light, from expansive starscapes to deep-sky detail.
Built to capture red nebulae
A dedicated IR cut filter tuned for Hα wavelengths, combined with powerful TruePic™ X processing, reveals vivid red nebulae and fine celestial detail, delivering stunning image quality from wide starscapes to deep-sky scenes.
Astro-tuned colour & custom modes
Preconfigured custom modes and dedicated color profiles make capturing the night sky effortless. From red nebulae to starry landscapes, optimized stacking, Starry Sky AF, and astro-tuned color deliver impressive results—beautifully rendered straight out of the camera.
Deep-sky detail, perfectly aligned
When Handheld High Res Shot is activated with the camera mounted on a tripod or equatorial mount, multiple exposures are combined into a 50MP image. Intelligent image alignment reduces noise and corrects star motion and tracking errors for crisp, high-resolution astrophotography.

Features that bring the night sky to life
From starlit skies to long exposures, the OM-3 ASTRO unlocks the magic of the night with Starry Sky AF, Night Vision Mode, and Live Composite—powerful features that make capturing stunning low-light images effortless, with no extra gear or guesswork.
Live Composite
Paint the night with stars, lightning, or light trails. Live Composite stacks only new light, allowing you to watch your masterpiece build in real time—without overexposure.
Starry Sky AF
A skill that takes years to master, now behind one button. Starry Sky AF locks sharp focus on stars, so you can capture stunning astro shots with ease.
Night Vision mode
Preserve your night vision during moonlit hikes or stargazing with a live view that remains visible in low light, allowing for stealthy shooting without disrupting your vision.
Compact and durable. Ready for night sky adventures
The OM-3 ASTRO is built for night sky adventures, with a lightweight, full-metal body under 500 g and IP53-rated durability. From starlit landscapes to remote deep-sky locations, it stands up to the elements so you can focus on capturing the celestial expanse.
IP53-certified weather-sealing
Shoot the night sky anywhere, anytime. With IP53-certified protection against dust, rain, and cold, your camera is ready to capture stars, nebulae, and celestial events in any conditions.
Compact & lightweight
Weighing under 500g, this camera is perfectly designed for night-sky photography—easy to carry to remote locations and built to capture the stars with precision and clarity.
USB power
Keep your OM-3 ASTRO powered through long nights under the stars. With USB-C PD charging, you can connect a power bank and continue shooting without interruption—perfect for extended astrophotography sessions in the field.
Capture the stars like never before with powerful in-camera features
Handheld High Res Shot
Shooting with Handheld High Res Shot when the camera is mounted on a tripod will produce composite images in which the diurnal motion of the stars is corrected.
Timelapse
Capture the motion of stars and planets, entirely in-camera. Produce smooth night-sky timelapses ready to export in stunning 4K resolution.
Colour profile control
Create vibrant night skies with preset color modes on the creative dial, designed for astrophotography. Easily apply optimal settings for red nebulae or starry landscapes, adjust saturation, highlights, and shadows, and save your favorite profiles.
Why Handheld High Res on a Tripod?
High Res Shot uses in-camera stacking to produce higher-quality images with greater detail and reduced noise.
By capturing and compositing multiple frames, OM SYSTEM’s High Res Shot function generates ultra-high-resolution images. While Handheld High Res Shot is typically used without support, fixing the camera to a tripod or equatorial mount allows astrophotography-style stacking to be completed in a single in-body process. This approach increases resolution and corrects star movement or tracking errors, resulting in cleaner, sharper images.
Tip:
When shooting fixed on a tripod, set the shutter speed so that the exposure time per frame is such that the stars appear as dots.
Remotely capture flawless night-sky shots with perfect stability
Use the OI.Share app or RM-WR2 remote controller to capture stars with pinpoint accuracy. Shoot long exposures, timelapses, and high-resolution astro images without touching the camera, keeping every frame sharp and stable.
RM-WR2 Wireless Remote Control Release
Wirelessly control your camera via Bluetooth using the RM-WR2 for precise, stable night-sky photography.
The free OI.Share App
Wireless remote control, camera live view on your mobile device screen, and browsing and importing images—even with the camera in your backpack. The OI.Share app does it all.
Color Profile Control
For the final touch, the OM-3 ASTRO’s color profile control enhances night skies straight out of the camera, emphasizing red tones so nebulae and stars stand out with dramatic, expressive impact.

Perfect your astrophotography with Body-Mount Filters
Two optional body-mount filters let you enhance your astrophotography directly at the sensor. Mounted inside the camera body, they work with any lens—even fisheye or wide-angle—so you can capture stunning night-sky images.
BMF-LPC01 Light Pollution Filter
Reduces artificial light interference, preserving true nebula and constellation colors for cleaner night-sky images.
BMF-SE01 Soft Filter
The Soft Filter enhances point light sources, enlarging and blurring stars to emphasize their color and presence while preserving optical resolution.
